to install use the same directions as below, just replace MBS with NPH and Mirrodin Besieged with Neil Patrick Harris.

if that doesn't help you, all hope is lost.

i hope i'm not stepping on anyone's toes posting there here. i just know that i wanted to find the information asap and a couple of my friends wanted to know how to update. so until goblin hero gets his up officially...

click the folder icon to the right of the text box labeled "Path to Spoiler" and select the text file you downloaded earlier

click the "Next Page" button

then click the "Add Edition" button. (doing this should let you know that 155 cards were successfully added!)

after this, click the library pane of MWS (where you search through cards)

from the file menu select File>Save Deck/Library

unfortunately i don't know what happens if this doesn't go right the first time... my suggestion is to overwrite your MWS directory with your backup you made (you made that backup, right?) and start over.

after updating the main database, the only thing left to do is open up the zip you downloaded containing all the card art, and unzip it to the pics folder where the rest of your card art is located!

now, just make sure MWS is closed (if not, close it)... then re-open it to see all the card art! DONE!
